She still notices what others miss. It is instinct, and it is also what pulls her into trouble.

Short, cropped hair in dark grey-streaked black, one hand resting against her chin as she looks out of the window. Her gaze is calm yet watchful, as if she cannot help observing.
A dark brown leather jacket over a navy shirt with a pen in the breast pocket, and a wristwatch. The look is practical and plain, with the air of someone who is off duty but never really switches off.
